HEAT FLOWS AND THERMAL EQUILIBRIUM

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What happens to the temperature of a hot object when it is placed in a cooler environment?

Back

The temperature of the hot object decreases as it loses heat to the cooler environment until thermal equilibrium is reached.

What is convection?

Back

Convection is the transfer of heat through liquids and gases caused by the movement of the fluid itself, where warmer, less dense areas rise and cooler, denser areas sink.

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum, such as heat from the sun reaching the Earth.

How does heat transfer occur in liquids?

Back

Heat transfer in liquids occurs primarily through convection, where warmer liquid rises and cooler liquid sinks.

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, even on a cold day.
